PV system is
the complete set of equipment used in converting solar energy into a useful electrical
energy.
A PV module is a number of solar cells connected together to give output electircal power. These cells are encapsulated to protect cells from harsh weather. The lifetime of PV module can be normally expected 20 years. For large PV systems, PV modules are connected in series and/or parallel to form a solar array.
The controller is the brain of a PV system. It is necessary to monitor and control the power going into and coming out of the battery. The controller in order to increase the batteries lifetime must prevent the PV module from overcharging and the battery from deep discharging.
As PV modules can only produce electricity during the day, it is necessary to store the energy generated by the PV modules in batteries.
The load is basically any equipment which requires electrical energy in order to operate light, television, water pump, radio and TV transmitters, are all example of loads. Each load requires a specific amount of power in order to work. The sum of the load requirements will determine the number of PV modules and batteries in a PV system and therefore the cost of the system.
Inverter convert DC (Direct Current) electricity into AC (Alternating Current) to run many common appliances and equipment such as TV, VCR, Refrigerators, Water Pump......etc.
The supporting structure holds the PV modules securely in place and is designed for ease of installation and long-term durability. |
